In this article we are going to explain in detail the pros and cons of another amazing set from Zinus. This set consists of the Zinus Sleep Master iCoil 12 inch euro top spring mattress and the BiFold box spring. As you probably know, Zinus is a manufacturer who provides high quality mattress solutions at extremely affordable prices. They are able to offer their products at such low prices thanks to their direct shipping method which cuts down the costs of middle men or distributors, as well as the fact that their products are manufactured in China. However, don’t let that fool you because Zinus products are actually one of the finest quality bedding items you will find on the market. To help you determine whether this set is a good choice for the money, we’ve put together this detailed review.

The Mattress Layers

The mattress included in this set is the Sleep Master iCoil 12 inch euro top spring mattress from Zinus. Within those 13 inches the mattress has four separate layers as well as a high quality cover. Going from top to bottom, the first layer of the mattress is a 1.5 inch layer of comfort foam. Beneath it is another 2 inch layer of comfort foam for enhanced comfort and softness. The third layer is a 0.5 inch layer of high density foam that provides additional support, along with the last layer which is a 7.5 inch base support layer of iCoil pocketed springs.

This set also contains the BiFold Box Spring, which is a metal bed frame that replaces a traditional box spring. As the name suggests, the box spring can be folded for easier transportation or storage. Therefore, the box spring can be stored in tight spaces and easily carried if you need to move it to another place. The fact that the box spring can be folded may denote that it is unstable and fragile but in reality this bed frame is actually much stronger than it looks. Made of high quality heavy gauge steel, the BiFold box spring is durable and supportive. Most importantly, there is no assembly required with this box spring, all you need to do is open and unfold it to be ready for use.

The Quality of Materials and Certification

Just like all Zinus Mattresses, the foam components of this mattress are CertiPUR-US certified. This means the foam layers are durable, long-lasting and perform very well. It is also important to mention that all CertiPUR-US certified mattresses are made of natural components instead of traditional chemicals. Therefore, this mattress is made using natural plant oil, active charcoal and green tea extracts that reduce off-gassing and maintain freshness. Besides the comfort foam and high-density foam, the mattress also contains a layer of highly durable coil springs which are individually pocketed to ensure good motion isolation. Lastly, one more component of the mattress is the knitted Jacquard cover with microfiber quilted fabric for additional softness.

How it feels and the Overall Sleep Experience

The Zinus Sleep Master coil euro top spring mattress of 12 inches is one of their comfort innovation mattresses that provide great motion isolation. If you’re sleeping with a restless partner it can get quite annoying waking up in the middle of the night because of motion transfer. With this Zinus mattress you won’t have to worry about being interrupted during your sleep thanks to the sturdy pocketed coil springs. These springs also provide customized support by conforming to the body of the sleeper, allowing comfort and good pressure relief.

In terms of firmness, this mattress is considered to be very firm. Only three and a half inches of comfort foam are not enough to soften the supportive firmness of the coil springs, which is why this mattress falls under the category of firm mattresses. If you’re not used to firmer surfaces, you may want to consider softer Zinus mattresses or get a memory foam mattress topper to better your sleep experience. As firm as this mattress is, it is great for relieving back pain and pressure points. The comfort this mattress provides will allow you to get a better night’s sleep without worrying about motion transfer. You can expect little to no off-gassing when opening the package, which is normal because the mattress is sealed without air ventilation. This odor will fade away quickly. Lastly, this Zinus mattress has no heat regulation components, except the breathable cover that enhances the airflow. Therefore, you can expect it to get a bit warm during higher temperatures.

The Zinus Sleep Master iCoil 13 inch euro box top spring mattress comes under $500 for queen.  Even though it is a bit more expensive than most other Zinus mattresses, this mattress will still save you a lot of money compared to similar ones on the market. In terms of shipping, Zinus does a great job delivering their products on time, if not even a few days earlier. Each mattress is shipped in a vacuum compressed packaging which significantly reduces its size. This may cause damage to the mattress unless you open it within 72 hours of receiving the package. As usual, the mattress will take about 48 hours to fully expand to its size and shape. The only drawback with the shipping here is the fact that the BiFold box spring, the second component of the set, may be shipped in a different box. This means you will receive the shipments separately and you will need to wait for the second shipment in order to complete your bedding setup. Finally, even though there is no trial period for this Zinus set, you will receive a worry-free warranty that covers all manufacturing defaults. The mattress has a 10 year warranty period while the box spring has a shorter, 5 year warranty period.


In conclusion, this Zinus set is a good bedding solution including both the mattress and the bed frame that replaces the traditional box spring. The customized comfort provided by the combination of foam and springs betters your night’s sleep and provides great pressure relief. If you’re used to firm mattresses and you want a permanent bedding solution at an affordable price, this Zinus set is a great option to consider. Even if you’re not used to firmer mattresses, you can still get a memory foam mattress topper to add some softness. However, if you prefer medium to soft mattresses, you may want to look at other Zinus products on the market. Luckily, Zinus offers an array of different mattresses that include all kinds of mattress materials and levels of firmness.
